:tn'rnnnoomne FLEXIBLE SHINGLE.

Application filed lanuary 17,1927. Serial No. 161,594.

This invention relates to a flexible'interlocking shingle and hasfor its primary object to afford a construction that lends itself readily to quick and accurate positioning and locking of the shingles.

A further purpose of the invention is to provide a structure of such form that positive interlocking of the shingles is afforded, and such that there are no loose portions of the shingle that can curl upwardly.

Another object is to provide a shingle so -formed that a. multiplicity of shingles can be out from a blank without waste of material and in a quick and economical manner.

Still an additional purpose is to afford an improved construction applicable to shingles made from all kinds of flexible or pliable material.

To these and other ends, the invention comprises the construction and arrangement that will appear from the accompanying drawings, when read in conjunctionwith the following description, the novel features being pointed out in the claims at the end of the specification.

In the'drawings:

Figure 1 is a plan view of a portion of a roof, covered with shingles made in accordance with a preferred embodiment of the invention;

Figure 2 is an enlarged plan view showing a shingle superposed on and cooperating with a pair of shingles therebeneath;

Figure 3 is a plan view of a single shingle constructed in accordance with a preferred embodiment of the invention;

Figure l is a sectional view on line 4-4: of Figure l, and

Figure 5 is a sectional View on line 5-5 of Figure 1.

Referring more particularly to the draw ings, in which like reference characters refer to corresponding parts throughout the sev eral views, eachshingle comprises a generally rectangular body portion 1 having tapered extensions 2 along one edge. Each tapered extension 2 is provided near its outer end with an approximately V-shaped cut affording a tongue 3, while 4 is a slit provided centrally of the body portion to receive the tongue of a superposed shingle. Each shingle is also provided at its ends with slits 5 aligning with corresponding slits in adjacent shingles, whereby two abutting ends of adjacent shingles afford a complete slit of a proper length to receive a tongue of a superposed shingle. i

In this fashion, one tongue of each shingle engagesinto a slit formed by the ends of two abutting and adjacent shingles positioned therebeneath and thus serves to lock said twoshingles. In positioning the shingles, they are arranged end to end as shown in Figure 2, after which a shingle is superposed in such fashion that one of its tongues 3 engages into the opening formed by the end slits 5 of the two under shingles while the other tongue 3. of the superposed shingle engages the slit 4 in the shingle therebeneath. It will be understood that the tongues 3 are bent downwardly, and extend beneath the lower shingle as shown in Figures 2 and 1-.

The complete roof is built up in the fashion described, starting at the bottom and working upwardly, and when completely assembled, the tapered extensions, in their overlapping relationship, give the eifect of a series of hexagons, and are effectually interlocked and held against upward curling by the engagement of their tongues with the slit-s in the shingles arranged thereunder. The arrangement described also effectually prevents any water or moisture from getting beneath the shingles and attacking the roof, while at the same time a tight, and completely interlocked covering'is afforded.

While I have described the invention with reference to the particular embodiment herein disclosed, it is not confined to the details set forth, and this application is intended to cover any modifications or departures coming within the intent of the improvement or the scope of the following claims.

I claim:

1. A flexible shingle comprising a generally rectangular body portion having aplurality of extensions along one edge, said extensions having approximately Veshaped cuts near their outer ends affording tongues engageable with slits in shingles positioned thereunder, and said body portion having a tongue-receiving slit disposed opposite the space between each two extensions and at each end, said slits at the ends aligning with similar slits in adjacent shingles to receive a tongue of a superposed shingle which thus cooperates with and locks two adjacent shingles positioned thereunder.

2. A flexible shingle comprising a substantially rectangular body portion having a plurality of like projections along one side thereof, a straight slit in the body portion opposite the space between each two projections and parallel to the side of said body portion, straight slits in the ends of said body portion in aline'ment with saidfirst named slits, so that when two shingles :are laid end to endthe slit in one end of one shingle valines with the slit in the adjacent end of the next shingle to form one continuous slit, and a plurality of connected slits near the free ends of said projections,

said connected :slits being so arranged as to 0 form in each of sald projections a comparatively ilong tapered tongue integrally .at-

tached to the shingle at its base and extend- -ing a substantial distance toward the main body portion of the shingle, so that when a plurality of such shingles are laid upon a sloping roof, one tongue of one shingle passes through the slits in the ends of two adjacent underlying shingles to aid in hold- .ing said shingles in alinement with each other, and theother tongues of said shingle pass through the straight slits in the body portions of underlying shingles, and all of said tongues after passing through said slits extend therefrom up the slope of the .roof for a substantial distance, thus firmly holdsigned my name.
